FIG. 1 shows an Internet Protocol Television (IPTV) system 100 including a client facing tier 102, an application tier 104, an acquisition tier 106, and an operations and management tier 108. Each tier 102, 104, 106, and 108 is coupled to one or both of a private network 110 and a public network 112. For example, the client-facing tier 102 can be coupled to the private network 110, while the application tier 104 can be coupled to the private network 110 and to the public network 112 such as the Internet. The acquisition tier 106 can also be coupled to the private network 110 and to the public network 112. Moreover, the operations and management tier 108 can be coupled to the public network 112.

The various tiers 102, 104, 106 and 108 communicate with each other via the private network 110 and the public network 112. For instance, the client-facing tier 102 can communicate with the application tier 104 and the acquisition tier 106 via the private network 110. The application tier 104 can also communicate with the acquisition tier 106 via the private network 110. Further, the application tier 104 can communicate with the acquisition tier 106 and the operations and management tier 108 via the public network 112. Moreover, the acquisition tier 106 can communicate with the operations and management tier 108 via the public network 112. In a particular embodiment, elements of the application tier 104 can communicate directly with the client-facing tier 102.

The client-facing tier 102 can communicate with user equipment via a private access network 166, such as an IPTV network. In an illustrative embodiment, modems such as a first modem 114 and a second modem 122 can be coupled to the private access network 166. The client-facing tier 102 can communicate with a first representative set-top box (STB) device 116 via the first modem 114 and with a second representative set-top box device 124 via the second modem 122. The client-facing tier 102 can communicate with a large number of set-top boxes over a wide geographic area, such as a regional area, a metropolitan area, a viewing area, or any other suitable geographic area that can be supported by networking the client-facing tier 102 to numerous set-top box devices. In one embodiment, the client-facing tier 102 can be coupled to the modems 114 and 122 via fiber optic cables. Alternatively, the modems 114 and 122 can be digital subscriber line (DSL) modems that are coupled to one or more network nodes via twisted pairs, and the client-facing tier 102 can be coupled to the network nodes via fiber-optic cables. Each set-top box device 116 and 124 can process data received from the private access network 166 via an IPTV software platform such as Microsoft® TV IPTV Edition.

The first set-top box device 116 can be coupled to a first display device 118, such as a first television monitor, and the second set-top box device 124 can be coupled to a second display device 126, such as a second television monitor. Moreover, the first set-top box device 116 can communicate with a first remote control 120, and the second set-top box device can communicate with a second remote control 128. In an exemplary, non-limiting embodiment, each set-top box device 116 and 124 can receive data or video from the client-facing tier 102 via the private access network 166 and render or display the data or video at the display device 118 or 126 to which it is coupled. The set-top box devices 116 and 124 thus may include tuners that receive and decode television programming information for transmission to the display devices 118 and 126. Further, the set-top box devices 116 and 124 can include an STB processor 170 and an STB memory device 172 that is accessible to the STB processor. In a particular embodiment, the set-top box devices 116 and 124 can also communicate commands received from the remote controls 120 and 128 back to the client-facing tier 102 via the private access network 166.

In an illustrative embodiment, the client-facing tier 102 can include a client-facing tier (CFT) switch 130 that manages communication between the client-facing tier 102 and the private access network 166 and between the client-facing tier 102 and the private network 110. As shown, the CFT switch 130 is coupled to one or more data servers 132 that store data transmitted in response to user requests, such as video-on-demand material. The CFT switch 130 can also be coupled to a terminal server 134 that provides terminal devices, such as a game application server and other devices with a common connection point to the private network 110. In a particular embodiment, the CFT switch 130 can also be coupled to a video-on-demand (VOD) server 136.

The application tier 104 can communicate with both the private network 110 and the public network 112. In this embodiment, the application tier 104 can include a first application tier (APP) switch 138 and a second APP switch 140. In a particular embodiment, the first APP switch 138 can be coupled to the second APP switch 140. The first APP switch 138 can be coupled to an application server 142 and to an OSS/BSS gateway 144. The application server 142 provides applications to the set-top box devices 116 and 124 via the private access network 166, so the set-top box devices 116 and 124 can provide functions such as display, messaging, processing of IPTV data and VOD material. In a particular embodiment, the OSS/BSS gateway 144 includes operation systems and support (OSS) data, as well as billing systems and support (BSS) data.

The second APP switch 140 can be coupled to a domain controller 146 that provides web access, for example, to users via the public network 112. The second APP switch 140 can be coupled to a subscriber and system store 148 that includes account information, such as account information that is associated with users who access the system 100 via the private network 110 or the public network 112. In a particular embodiment, the application tier 104 can also include a client gateway 150 that communicates data directly to the client-facing tier 102. In this embodiment, the client gateway 150 can be coupled directly to the CFT switch 130. The client gateway 150 can provide user access to the private network 110 and the tiers coupled thereto.

In a particular embodiment, the set-top box devices 116 and 124 can access the system via the private access network 166 using information received from the client gateway 150. The private access network 166 provides security for the private network 110. User devices can access the client gateway 150 via the private access network 166, and the client gateway 150 can allow such devices to access the private network 110 once the devices are authenticated or verified. Similarly, the client gateway 150 can prevent unauthorized devices, such as hacker computers or stolen set-top box devices, from accessing the private network 110 by denying access to these devices beyond the private access network 166.

For example, when the set-top box device 116 accesses the system 100 via the private access network 166, the client gateway 150 can verify subscriber information by communicating with the subscriber and system store 148 via the private network 110, the first APP switch 138 and the second APP switch 140. Further, the client gateway 150 can verify billing information and status by communicating with the OSS/BSS gateway 144 via the private network 110 and the first APP switch 138. The OSS/BSS gateway 144 can transmit a query across the first APP switch 138, to the second APP switch 140, and the second APP switch 140 can communicate the query across the public network 112 to the OSS/BSS server 164. After the client gateway 150 confirms subscriber and/or billing information, the client gateway 150 can allow the set-top box device 116 access to IPTV content and VOD content. If the client gateway 150 cannot verify subscriber information for the set-top box device 116, such as because it is connected to a different twisted pair, the client gateway 150 can deny transmissions to and from the set-top box device 116 beyond the private access network 166.

The acquisition tier 106 includes an acquisition tier (AQT) switch 152 that communicates with the private network 110. The AQT switch 152 can also communicate with the operations and management tier 108 via the public network 112. In a particular embodiment, the AQT switch 152 can be coupled to a live acquisition server 154 that receives television content, for example, from a broadcast service 156. Further, the AQT switch can be coupled to a video-on-demand importer server 158 that stores television content received at the acquisition tier 106 and communicate the stored content to the client-facing tier 102 via the private network 110.

The operations and management tier 108 can include an operations and management tier (OMT) switch 160 that conducts communication between the operations and management tier 108 and the public network 112. In the illustrated embodiment, the OMT switch 160 is coupled to a TV2 server 162. Additionally, the OMT switch 160 can be coupled to an OSS/BSS server 164 and to a simple network management protocol (SNMP) monitor 167 that monitors network devices. In a particular embodiment, the OMT switch 160 can communicate with the AQT switch 152 via the public network 112.

In a particular embodiment during operation of the IPTV system, the live acquisition server 154 can acquire television content from the broadcast service 156. The live acquisition server 154 in turn can transmit the television content to the AQT switch 152 and the AQT switch can transmit the television content to the CFT switch 130 via the private network 110. Further, the television content can be encoded at the D-servers 132, and the CFT switch 130 can communicate the television content to the modems 114 and 122 via the private access network 166. The set-top box devices 116 and 124 can receive the television content from the modems 114 and 122, decode the television content, and transmit the content to the display devices 118 and 126 according to commands from the remote control devices 120 and 128.

Additionally, at the acquisition tier 106, the VOD importer server 158 can receive content from one or more VOD sources outside the IPTV system 100, such as movie studios and programmers of non-live content. The VOD importer server 158 can transmit the VOD content to the AQT switch 152, and the AQT switch 152 in turn can communicate the material to the CFT switch 130 via the private network 110. The VOD content can be stored at one or more servers, such as the VOD server 136.

When a user issues a request for VOD content to the set-top box device 116 or 124, the request can be transmitted over the private access network 166 to the VOD server 136 via the CFT switch 130. Upon receiving such a request, the VOD server 136 can retrieve requested VOD content and transmit the content to the set-top box device 116 or 124 across the private access network 166 via the CFT switch 130. In an illustrative embodiment, the live acquisition server 154 can transmit the television content to the AQT switch 152, and the AQT switch 152 in turn can transmit the television content to the OMT switch 160 via the public network 112. In this embodiment, the OMT switch 160 can transmit the television content to the TV2 server 162 for display to users accessing the user interface at the TV2 server. For example, a user can access the TV2 server 162 using a personal computer (PC) 168 coupled to the public network 112.

The domain controller 146 communicates with the public network 112 via the second APP switch 140. Additionally, the domain controller 146 can communicate via the public network 112 with the PC 168. For example, the domain controller 146 can display a web portal via the public network 112 and allow users to access the web portal using the PC 168. Further, in an illustrative embodiment, the domain controller 146 can communicate with at least one wireless network access point 178 over a data network 176. In this embodiment, each wireless network access device 178 can communicate with user wireless devices such as a cellular telephone 184.

In a particular embodiment, the set-top box devices can include an STB computer program 174 that is embedded within the STB memory device 172. The STB computer program 174 can contain instructions to receive and execute at least one user television viewing preference that a user has entered by accessing an Internet user account via the domain controller 146. For example, the user can use the PC 168 to access a web portal maintained by the domain controller 146 via the Internet. The domain controller 146 can query the subscriber and system store 148 via the private network 110 for account information associated with the user. In a particular embodiment, the account information can associate the user's Internet account with the second set-top box device 124. For instance, in an illustrative embodiment, the account information can relate the user's account to the second set-top box device 124 by associating the user account with an IP address of the second set-top box device, with data relating to one or more twisted pairs connected with the second set-top box device, with data related to one or more fiber optic cables connected with the second set-top box device, with an alphanumeric identifier of the second set-top box device, with any other data that is suitable for associating the second set-top box device with a user account, or with any combination of these.

The STB computer program 174 can contain instructions to receive many types of user preferences from the domain controller 146 via the access network 166. For example, the STB computer program 174 can include instructions to receive a request to record at least one television program at a video content storage module such as a digital video recorder (DVR) 182 within the second set-top box device 124. In this example embodiment, the STB computer program 174 can include instructions to transmit the request to the DVR 182, where the television program(s) are recorded. In an illustrative embodiment, the STB computer program 174 can include instructions to receive from the DVR 182 a recording status with respect to one or more of the television programs and to transmit at least one message regarding the status to a wireless device, such as the cellular telephone 184. The message can be received at the CFT switch 130, for instance, and communicated to the domain controller 146 across the private network 110 via the second APP switch 140. Further, the domain controller 146 can transmit the message to the wireless data network 176, directly or via the public network 112, and on to the wireless network access point 178. The message can then be transmitted to the cellular telephone 184. In an illustrative embodiment, the status can be sent via a wireless access protocol (WAP).

FIG. 2 shows an exemplary embodiment of an electronic programming guide (EPG) 200. The EPG 200 provides television viewers with on-screen television schedule information. EPG 200 may also include additional information, such as advertisements, detailed program descriptions, programming, or any combination thereof. The programming information is preferably displayed in a grid format, including columns 202 through 208. Column 202 displays the various channels. The list of channels may include all channels available, only those channels to which the viewer is subscribed, or a subset of favorite channels preselected by the viewer. Columns 204, 206, and 208 can indicate what is showing on the channels listed in column 202 in half hour increments. For example, titles of programs can be displayed within the columns 204, 206, and 208. Additionally, a brief description of the program may be displayed. For programs spanning multiple half hour increments, the title and description may be displayed across more than one of columns 204, 206, and 208. The time corresponding to the half hour increments is displayed in a row 210 across the top of EPG 200. Typically, more channels are available than can be shown at one time. Accordingly, the grid may be scrolled up or down through additional channels. Further, a user may scroll the grid to the left or right to view programming choices at different times.

FIG. 3 illustrates an exemplary method of searching for programming content based on information within a television commercial. At 302, an STB such as STB 116 can detect a commercial. Various techniques are known in the art to identify the beginning and end of television commercials. At 304, the STB can analyze the commercial data to identify an advertised programming. In an exemplary embodiment, the commercial may be a network advertisement promoting a movie or television series to be broadcast on the network later in time. In an alternate embodiment, the commercial may be a studio commercial advertising a movie that is soon to be available by VoD or download. In yet another embodiment, the commercial may be an advertisement promoting for-pay programming, such as a boxing match that is available as PPV.

The STB can identify the title of the programming or other identifying information, such as an actor or director associated with the programming, based on the content of the commercial. In an embodiment, the commercial can include metadata that includes identifying information. In another embodiment, the commercial may not include metadata and the STB can extract the identifying information from audio and video portions of the commercial. In an alternate embodiment, the commercial as provided by a source, such as the studio or the broadcast network, may not include metadata. Network servers, such as video content servers 180 or live acquisition server 154, may extract the identifying information from the audio and video portions of the commercial. Alternatively, the network servers may match a commercial signature to a database to determine the identifying information. Metadata, including the identifying information, may be added to the commercial prior to delivery to the STB.

At 306, the STB can search for content matching the identifying information. For example, the STB may search the available EPG for occurrences of a series advertised by the commercial. In another example, the STB may search a content database, such as a VoD database or a database of content available for download, to determine if a movie advertised by a commercial is available. At 308, the STB may provide a list of content matching the identifying information. In an embodiment, the STB may display a dialog box indicating that matching content is available. A viewer may select to see a list of available content and the STB may provide information about the matching content, such as the source and a time it is available. The information may also include a cost and identify commercial-free content. At 310, the STB can begin playback of currently available content or schedule a recording for content available at a later time. Additionally, the STB may provide an option to set up a recurring recording for regularly scheduled series.

FIG. 4 illustrates an exemplary method of searching for programming content based on information within a television commercial. At 402, an STB such as STB 116 can detect a commercial. At 404, the STB can analyze the commercial data for identifying information. The identifying information can include a title, a broadcast time, and channel, or other information such as genre. The identifying information can be determined from metadata associate with the commercial or from a video or audio portion of the commercial.

At 406, the STB can provide an option to search for the advertised content or content similar to the advertised content. At 408, a viewer may choose to search for the advertised content. For example, the commercial may be advertising a series premiere to be broadcast later in the week. The STB may identify the content based on the title of the series, the channel that will broadcast the series, and the time the series is scheduled for broadcast. The STB may also search a database of content to determine if the series will be available for download. At 410, the STB may display viewing choices to the user. The display may include the title of the content, when the content will be available, and an option to view or record the content when it is available. In an embodiment, a series scheduled for broadcast may also be provided as a downloadable purchase. The display may list both the scheduled broadcast and the option to download the content. For a downloadable series, the STB may provide the option to purchase and later download an entire season as episodes become available. The viewer may choose a preferred source of the content. At 412, the STB can begin playback of currently available content or schedule a recording for content available at a later time. Additionally, the STB may set up a recurring recording for regularly scheduled series.

Returning to 406, a viewer may choose to search the EPG and content databases for related content, as illustrated at 414. In an embodiment, the commercial may be advertising a movie soon to be in theaters. Related content may include content having a similar genre or content associated with an actor or director involved in the advertised movie. Additionally, if the movie is a sequel or a remake, related content may include previous movies. In another embodiment, the commercial may be advertising a product, such as a book. Related content may include adaptations of the author's previous books or movies and series with which the author is associated. In yet another embodiment, the commercial may be advertising a product line, such as a clothing line, named after or endorsed by an actor. Related content may include programs with which the actor is associated.

At 416, the STB may display the related content to the user. The display may include the title of the related content, when the related content will be available, and an option to view or record the related content when it is available. At 418, the STB can begin playback of currently available related content or schedule a recording for related content available at a later time. In an embodiment, the STB may download related content available for purchase or rental.

FIG. 5 illustrates an exemplary method for analyzing commercial data to obtain identifying information. At 502, a STB may detect a commercial. At 504, the STB may determine if metadata is associated with the commercial. When metadata is associated with the commercial, the STB can extract identifying information related to the commercial from the metadata. The identifying information may include a title, a genre, a list of people associated with the advertised product, or similar information. At 506, the STB can use the identifying information to search for content related to the commercial.

Returning to 504, when there is no metadata associated with the commercial, the STB may determine if the commercial includes closed captioning information, as illustrated at 508. When the commercial includes closed captioning information, the STB may analyze text extracted from the closed captioning information, as illustrated at 510. For example, a commercial advertising a television series may contain closed captioning information including the title of the series and the time and channel of the scheduled broadcast. At 506, the STB can use the identifying information to search for content related to the commercial.

At 512, when there is no closed captioning information associated with the commercial, the STB may determine if a video portion of the commercial includes text. For example, a commercial advertising a broadcast program may include text indicating a channel and time for the broadcast. At 514, when the video portion of the commercial includes text, the STB may utilize optical character recognition software to extract the text from the video portion of the commercial. At 510, the text extracted from the video portion of the commercial may be analyzed to obtain identifying information.

At 516, when the video portion of the commercial does not include text, the STB may isolate speech form the audio portion of the commercial. For example, an announcer may identify a title, a broadcast time, and a broadcast channel for a made-for-TV movie being advertised by the commercial. At 518, the STB may utilize speech recognition software to convert the speech to text. Various techniques are known in the art for speech recognition. At 510, the text extracted from the video portion of the commercial may be analyzed to obtain identifying information.

In an alternate embodiment, network servers, such as video content servers 180 or live acquisition server 154, may detect the commercial and extract identifying information from the commercial. The network servers may provide the identifying information to the STB so that the STB can search for related content. Alternatively, the network servers may search for the related content and provide a list of related content to the STB. The STB may compare the list of related content to a set of subscription options to provide the viewer with a list of available related content.

In another embodiment, network servers may provide a database of identifying information to the STB. The STB may use a signature of the commercial, such as a hash of the digital information, to access identifying information related to the commercial from the database.
